The pivot section 111 of each bracket 1 has a shaft hole 113 for accommodating the corresponding shaft 53 so that the bracket 1 can rotate around the shaft 53 .

Referring to FIGS. 1 to 3 , the auxiliary extension frames 6 are respectively slidably arranged on the outer groove rails 34 along the outer groove rails 34 and are respectively connected to the sliding surfaces 121 of the brackets 1 in a slidable manner. Surface 121. In this embodiment, each auxiliary extension frame 6 has a rail sliding portion 61 that is arc-shaped to match the corresponding outer groove rail 34 and a connecting sliding portion that extends from one end of the rail sliding portion 61 along the first direction D1. 62. The connecting sliding part 62 abuts against the corresponding sliding surface 121 and can slide relative to the sliding surface 121, and has a through groove 621 corresponding to the mounting holes 122 and extending along the first direction D1 for being provided in the corresponding mounting holes 122. The locking piece of the mounting hole 122 passes through.

Referring to Fig. 6 to Fig. 8, these brackets 1 can be in an unfolded state (as shown in Fig. 6) that these support surfaces 13 are coplanar and these support surfaces 13 are in a retracted state opposite and spaced apart (such as Figure 8) conversion.

Also referring to Fig. 9 to Fig. 11, during the transition of the brackets 1 from the unfolded state to the folded state, on the inner side of the track seat 3, the sliding keys 5 of the rotating shafts are linked with the brackets 1 and first move along the The inner groove rails 43 slide and then drive the rail sliding keys 4 to slide along the inner groove rails 32 . In this embodiment, each inner groove rail 43 has an inner end 431 relatively close to the other inner layer groove rail 43 and an outer end 432 opposite to the inner end 431, and a part of the inner end 431 is bounded by the inner end 431. Defined by track seat 3. As shown in FIG. 9 , when the brackets 1 are in the unfolded state, the first ends 511 of the shaft sliding keys 5 are located at the inner ends 431 of the inner grooved rails 43 and abut against the rail seat 3 . As shown in FIG. 10 , when the brackets 1 pivot about 45 degrees, the shaft sliding keys 5 slide along the inner groove rails 43 until the second ends 512 are positioned at the inner layer groove rails 43 The outer end 432 abuts against the corresponding track sliding key 4 to define the outer end 432. At the same time, referring to FIG. 5, the resisting blocks 52 of the rotating shaft sliding keys 5 slide along the avoidance grooves 44 to the corresponding avoidance grooves. 44 against an abutting end 441, and abut against the track feather key 4 to define the abutting end 441. As shown in Figure 11, when the brackets 1 continue to rotate to the folded state, the shaft sliding keys 5 respectively push the corresponding rail sliding keys 4 to slide along the inner groove rails 32, and the rail sliding keys 4 protrude from the open end of the inner groove rails 32 from the rail base 3 . During the transition of the brackets 1 from the unfolded state to the folded state, the pivotal sections 111 of the brackets 1 move together with the shafts 53 of the sliding keys 5 and take the corresponding shafts 53 as the axis Pivot, and these shaft rods 53 move along these inner layer groove rails 43 first along with these rotation shaft sliding keys 5 and then move along these inner layer groove rails 32, and then make the axis centers of these supports 1 follow the shaft rods 53's moving position changes. In this embodiment, the rotation centers of the inner groove rails 32 and the inner layer groove rails 43 are different, so that the rotation angle of the brackets 1 during the rotation process can be closer to the bending of the flexible display screen The demand is to reduce undue stretching force and extrusion force on the flexible display screen, thereby reducing the risk of damage to the flexible display screen. In addition, the curvatures of the inner grooves 32 and the inner grooves 43 can be the same or different, and can be adjusted according to the properties and requirements of different flexible display screens.

Referring to Fig. 6 to Fig. 8 again, during the transition of the supports 1 from the unfolded state to the folded state, on the outside of the track seat 3, the auxiliary extension frames 6 are linked with the supports 1 and respectively move along the Wait for outer groove rail 34 to slide. As shown in Figure 8, in the folded state, the brackets 1 can slide relative to the auxiliary extension frames 6 to the direction away from the track seat 3, that is, the top ends of the brackets 1 are higher than the auxiliary extensions. top of frame 6. Moreover, as shown in FIG. 11 , the brackets 1 drive the shaft sliding keys 5 together with the track sliding keys 4 to protrude from the open ends of the inner groove rails 32 to the track seat 3 . Since the brackets 1 have a degree of freedom to slide relative to the auxiliary extension frames 6, and the brackets 1 are pivotally connected to the sliding keys 5 of the rotating shafts, and have a degree of freedom to rotate relative to the sliding keys 5 of the rotating shafts, so the When the brackets 1 slide relative to the auxiliary extension frames 6, they also rotate relative to the shafts 53 of the sliding keys 5 of the rotating shafts, and simultaneously drive the shafts 53 to move so that the positions of the shafts 53 can be higher than the track seats. 3 on top. In this way, the protruding amount of the rotating shaft sliding keys 5 and the track sliding keys 4 out of the track seat 3 is increased, that is, the displacement of the rotating shaft sliding keys 5 and the track sliding keys 4 is increased. In this way, the tops of the brackets 1 are farther away from the top surface of the track seat 3, that is, the distance between the tops of the supports 1 and the top surface of the track seat 3 is increased, so that the flexible The display screen is stretched upwards to reduce the curvature near the bend of the track seat 3 . In other words, adjust the rotation centers and curvatures of the inner groove rails 32 and the inner layer groove rails 43 to adjust the moving tracks of the shaft sliding keys 5 and the track sliding keys 4, thereby affecting the brackets 1 and the The relative sliding amount of the auxiliary extension bracket 6 is equal to meet the properties and requirements of different flexible display screens.

To sum up, by adjusting the rotation centers and curvatures of the inner groove rails 32 and the inner layer groove rails 43, the moving tracks of the shaft sliding keys 5 and the track sliding keys 4 are adjusted, thereby affecting the The relative sliding amounts of the brackets 1 and the auxiliary extension brackets 6 can be applied to different flexible display screens to meet the properties and requirements of different flexible display screens.
